A manufacturer produces a type of cylinders with diameter of 4 inches. To determine whether the process is in statistical control, the operations manager randomly selects 10 samples with each sample containing 4 cylinders. The mean and range for each sample are given in the table below. Sample 1 2 3 4 5 6 7 8 9 10 Mean 4.01 3.98 4.00 3.99 4.04 3.98 4.02 3.99 3.98 4.01 Range 0.04 0.06 0.02 0.03 0.06 0.02 0.02 0.04 0.05 0.06 Answer the following questions based on the table. For the X-chart: Upper Control Limit (UCL) = A : Lower Control Limit (LCL) = Use 2-decimal accuracy for the final answer, e.g., 0.12, when necessary. A/ Question 5 (4 points) For the R-chart: Upper Control Limit (UCL) = A : Lower Control Limit (LCL) = Use 2-decimal accuracy for the final answer, e.g., 0.12, when necessary. AJ Question 6 (4 points) The process is in statistical control. This statement is cannot tell whether it is true or false; more information is needed. true false
